注：為便于計算，在上表中提供的軸承額定負荷是以500轉/分的速度運轉3000小時為基礎，即L10壽命，但較大的軸承速度卻取決于軸承的尺寸及負荷的程度，而速度有可能低于500轉/分.
In order to make it easy for calculation, the load rating noted in the above file is based on working 3000h at the speed of 500r/m, i.e. L10 life. While the limited bearing speed is depended on bearing dimension and the real load, and the speed is possible to be under 500r/m
